ChessRiddle

ChessRiddle is not your average tactics trainer. Instead of guessing single moves, you train real calculation – as close to a real game as possible.

🧠 WHAT MAKES CHESSRIDDLE DIFFERENT
• The board stays static: you calculate the whole line in your head instead of trying moves on the board.
• You enter the complete variation tree to prove you calculated the entire line – no move-guessing.
• Mixed Mode: tactics and positional play combined, just like a real game – you first decide whether the position is tactical or positional.
• Every solution is validated server-side with Stockfish.

That sets ChessRiddle apart from the hundreds of pure tactics trainers where a well-guessed first move is enough.

🎯 SIX TRAINING MODES
• Tactics – Find classic combinations and tactical motifs
• Mixed – Tactics and positional play in one mode: assess first, then solve – just like at the board
• Pieceless – Solve puzzles without visible pieces and train your board vision
• Visualization – Calculate announced moves (pre-moves), then solve the position
• Opening Blunder – Spot and punish typical opening mistakes
• Position Evaluation – Estimate who stands better
